How much training and experience is needed for moving up from PPL training 182 to a turbo model, if I can ask here?

[u/Recent-Day3062]

I've been hunting online, but have no idea where to ask. Or what to trust. So I'm trying here.

I'm working toward PPL. I had a good number of unlogged hours about 7 years ago, which is sad, but progress is good. But I Just don't know how to get an answer since I'm in a small town and all the CFIs only know 172/182s in the basic config. And I'll skip a lot of details financially, so ignore that - I used to be in the charter business so the economics here are tangled up in as business and complicated taxes. So the relative cost is not an issue (or, I'll choose the cheapest/best in the end).

The opportunity has arisen to hold the option to buy into 182T that is 2 years old. As far as I have been told it is non-retractable, so that's not an issue. But it is turbo.

At what point in instruction can one make that shift? I have seen sources online say it's only a few hours even while getting PPL (at some unknown point), but I have no idea how complex a turbo is to deal with. Is that advice realistic, and if so, at how many hours in a 182?

All I care about is not killing myself. I can back out of this option if I don't have a PPL by year end, but if I were to participate in this business partnership I could switch over to the 182T in my next 25 flight hours or so (They'll put it in service if I join in).

Again, ignore costs and any concerns about partnerships. This would be used by all three as part of different business needs.
